| titleOfInvention | Phosphor powder and light emitting device |
| abstract | A certain aspect of the present invention is a phosphor powder comprising Eu-activated β-sialon phosphor particles as a main component. In the present invention, in the phosphor powder not subjected to ultrasonic homogenizer treatment, the median diameter (D 50 ) measured by wet measurement using a laser diffraction type particle size distribution analyzer is D1, and is carried out under the following conditions In the above-mentioned phosphor powder subjected to ultrasonic homogenizer treatment, when the median diameter (D 50 ) measured by wet measurement using a laser diffraction particle size distribution analyzer is D2, D1/D2 is 1.05 or more and 1.70 or less. provides (Conditions) A dispersion in which 30 mg of the phosphor powder is uniformly dispersed in 100 ml of an aqueous solution of sodium hexametaphosphate having a concentration of 0.2% is placed in a columnar container having an inner diameter of 5.5 cm at the bottom. Next, in the dispersion liquid, in a state in which a cylindrical chip having an outer diameter of 20 mm is immersed in an ultrasonic homogenizer by 1.0 cm or more, the dispersion liquid is irradiated with ultrasonic waves at a frequency of 19.5 kHz and an output of 150 W for 3 minutes. |
